Carqueja (Baccharis genistelloides)
Carqueja showed in vitro antiviral actions against Herpes simplex I and Vesicular stomatitis viruses at low dosages in laboratory research. Researchers in Texas published that a water extract of carqueja provided an in vitro inhibition of HIV virus replication in T-cells. In subsequent research, they've attributed this anti-HIV effect to a single chemical they found in the water extract of carqueja called 3,5-dicaffeoylquinic acid and reported that this plant chemical is a potent inhibitor of HIV at dosages as low as only 1 mcg/ml. See page B-15 for more information on carqueja.*

Chanca piedra (Phyllanthus niruri, amarus)
Chanca piedra has been the subject of much study with Hepatitis B. A review of 22 randomized trials by The Cochrane Hepato-Biliary Research Group suggests it has, “a positive effect on clearance of serum HBsAg (Hepatitis B surface antigen) comparable to interferon and was better than nonspecific treatment or other herbal medicines for HBV and liver enzyme normalization." Several other studies indicated chanca piedra has antiviral actions against HIV-1. For more information on chanca piedra, see page B-16.*
